Move the implementation of __mp_lock (biglock) into machine dependent
code. At this moment all architectures get the copy of the old code
except i386 which gets a new shiny implementation that doesn't spin
at splhigh (doh!) and doesn't try to grab the biglock when releasing
the biglock (double doh!).
Shaves 10% of system time during kernel compile and might solve a few
bugs as a bonus.
Other architectures coming shortly.
